DAVID K. BRYSON, OF PITTSBURG, PENNSYLVANIA.

WAVE-POWER MOTOR.

SPECIFICATION forming part of Letters Patent N 0. 711,758, dated October21, 1902.

Application filed February 7, 1902. Serial No. 93,005. (No model.)

To all whont it may concern: 7 Be it known that I, DAVID K. BRYSON, acitizen of the United States of America, residing at Pittsburg, in thecounty of Alleghenyand State of Pennsylvania,have invented certain newand useful Improvements in Wave- Power Motors, of which the following isa specification, reference being had therein to the accompanyingdrawings.

This invention relates to certain new and useful improvements inwavemotors, and has for its object a motor which will utilize thehorizontal as well as the vertical motion of the waves.

My invention has for its further object a wave-motor wherein thedirection of the propeller means shall at all times remain inva riable,irrespective of the direction in which the waves are running.

The invention further resides in the simplicity and economical featuresof construction, the comparative inexpense to manufacture, and theefficient operation.

With the above and other objects in view the invention consists in thenovel combina tion and arrangement of parts to be hereinafter more fullydescribed, and specifically pointed out in the claims. 7

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this speciflcation,and whereinlike numerals of reference indicate like parts throughout the severalviews,in which-'- Figure 1 is a perspective view of my invention,showing the staggered arrangement of the series of motors. Fig. 2 is acentral vertical sectional view taken on the line 22 of- Fig. 1. Fig. 3is an underneath plan view of the guide-rollers carried by the float.-'Fig. 4 is a side elevation of one of the sprocketwheels. Fig. 5 isahorizontal sectional View taken on the line 3 3 of Fig. 2. Fig. 6 is ahorizontal sectional view on the line 4 4 of Fig. 2. Fig. 7 is a topplan View of the rocking frameand the guide-rollers carried thereby.

In order to afiord a'rigid structure for the purpose of supporting theseries of power units, I embed within the bed of the body of water themotion of which is to be utilized to actuate the power units a series ofstandards 1, carrying suitably-spaced beams 2 and a transverse bar 3 attheir upper end.. This side of the float or casing 12.

rigid frame may be constructed in various manners, and the materialemployed in connection therewith may also vary. Shaft-supports 4 arecarried by the frame and have a revoluble shaft 5, carrying a fly-wheel6 and a drive-wheel 7, connected thereto.

Between the beams 2 is mounted a series of rocking frames 8, which arepivotally mounted as shown at 9. Mounted within this rocking frame aretwo pairs of diametrically-arranged guide-rollers 10 11, the purpose ofwhich will be fully hereinafter set forth.

' The float or casing 12 is perfectly air-tight and is preferably of anannular form with convexed upper and lower faces. The upper face of thisfloat or casing 12 has a suitable inlet 14: therein, closed by means ofthe plug 15, whereby access to the interior may be had in order to placea suflicient quantity of water or any other liquid therein, the quantityof liquid varying according to the specific gravity of the same, but inall cases being such as-will cause the float or casing to havesubstantially one-half of its height submerged in the body of water. Tothe lower side of this casing is a depending flange 15, surrounding aseries of antifriction-rollers 16, which are revolubly carried by thebottom of the float or casing 12. A like flange 17 is carried by theupper side of the casing and likewise surrounds a series ofantifrictionrollers 18, revolubly carried by the upper A tube 19 has itsupper end carrying a yoke 20, the upper ends of the yoke being pivotedto the sides of the rocking frame 8. The lower end of this tube 19carries a collar 21, the lower end 22 of-which is bent outwardly to forman annular flange which engages a series of outwardly-extending fins 23,carried by the collar 21. Downwardly-extending brackets 24, carryingantifrictio'n-rollers 25, are carried by this annular flange 22 of thecollar 21.

To the drive-shaft 5 is keyed a pair of ratchet-wheels 26 and 27,- whichare adapted to be engaged by the spring-pressed pawls 28 and 29, carriedby the loosely mounted sprocket-wheels 30 and 31 of the drive-shaft 5.The loosely-mounted sprocket-wheel 31 has a chain 32, carrying asuitable weight 33 at its one end mounted thereon, the other end of thechain passing through the tube 19 and carries the ordinary chain 34: atits lower end this chain passing downwardly through the collar 21between the several antifrictionrollers 25 and carries a hook 35 at itslower end which is engaged by the staple 36 on the upper end of the post37, the latter being rigidly affixed in the bed of the body of water.

To the upwardly-extending flange 17 of the float or casing 12 ispivotally secured a yoke 38, the upper end of which has secured theretoa sprocket-chain 39, which extends upwardly between the guide-rollers 10and 11 over the loosely-mounted sprocket-wheel 31 and from thence passesdownwardly and carries a weight 40 at its lower end.

It will be noted that the float 12 is slidingly mounted upon the tube 19by means of a sleeve 41, which is rigidly attached to the float orcasing 12. This casing in its movement upon the tube 19 will bematerially furthered in its ease of action by means of the guide-rollersl6 and 18, which contact with the periphery of the tube 19. I desire tocall attention to the fact that any number of these floats may beemployed in connection with the shaft in order to propel the latter, the

number being dependent upon the amount of power desired. '1 find whenmore than one float is employed that it is highly advantageous to givethe same a zigzag or staggered arrangement,as clearly illustrated inFig. 1 of the drawings.

We will assume for the purpose of illustration that the several floatshave been placed in their respective positions, as previously described,in which instance the latter are in a position to utilize the variousmotions of the waves. The up and down motion of the waves, or rather thevertical motion of the same, will cause the float 12 to ride up and downupon the tube 19, which will cause the weight 40 to move therewith. Uponthe upward movement of the float the sprocketchain will propel thesprocket-wheel in the direction from left to right, and upon thedownward movement of the float the springpressed pawl will engage in theteeth of the ratchet-wheel and cause the shaft 5 to revolve. Theinvention also aims to utilize the horizontal motion of the waves-thatis, the movement from said right to left or left to right or in a planetransverse to that direction, which movement of the float will cause thetube to move therewith, the tube moving about its pivoted connectionwith the rocking frame. This motion of the tube and the float will causethe rollers 25 to engage with the chain 34:, which is rigidly secured atits lower end to the post 37, and move the chain in a horizontaldirection, which is made possible by the rocking frame having a pivotalmovement. This horizontal motion of the tube and the float will causethe sprocketchain 32 the ratchet-wheel, and thus revolve the shaft 12.It will be noted that when the vertical movement of the waves isutilized the downward motion of the float is the power-stroke, causingthe pawl to engage in the ratchetwheel and revolve the shaft 5, and whenthe horizontal motion of the waves is utilized the outward movement ofthe float is the powerstroke, the weights in both instances merelyserving to take up the slack in the sprocketchain, thereby causing thelatter to engage in the teeth of the sprocket-wheels at all times. Thefins 23 serve the purposeof steadyingor retardin g the horizontal motionof the tube carrying the float when it is desired to utilize thevertical movement of the float only, which relieves the frame of anystrain which would result were the lower end of the tube rigidly affixedto the bed of thebody of water. I desire to call attention to the factthat this double action of the motor may be carried onsimultaneouslythat is, the tube and float may move to the horizontaldirection simultaneously with the up-and-down movement of the floatwhichwill utilize both the vertical and horizontal motion of the waves andcause delivery of power on the shafts to be more constant, the powerfrom the downstroke commencing where the power from the outward orhorizontal stroke stops.

1' have illustrated in the accompanying drawings the most practicalembodiment of my invention; but I do not wish to limit myself to theexact construction as shown and described, since it is obvious thatvarious minor changes in the details of construction and combination ofparts may be made without departing from the general spirit and scope ofmy invention.
